Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products,

Subcommittee SC 1, Rubber and plastics hoses and hose assemblies.

This fifth edition cancels and replaces the fourth edition (ISO 1402:2009), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— The tolerances of the pressure given in the figure 3 and relative clause 7.2.2, 8.1 and 8.2.

— A description of the failure mode in the clause 8.3.
A list of all parts in the ISO 1402 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

DRAFT INTERNATIONAL STANDARD ISO/DIS 1402:2020(E)
Rubber and plastics hoses and hose assemblies —
Hydrostatic testing
1 Scope

This International Standard specifies methods for the hydrostatic testing of rubber and plastics hoses

and hose assemblies, including methods for the determination of dimensional stability.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 4671, Rubber and plastics hoses and hose assemblies — Methods of measurement of the dimensions of

hoses and the lengths of hose assemblies

ISO 7751, Rubber and plastics hoses and hose assemblies — Ratios of proof and burst pressure to maximum

working pressure
ISO 8330, Rubber and plastics hoses and hose assemblies — Vocabulary

ISO 23529, Rubber — General procedures for preparing and conditioning test pieces for physical test methods

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 8330 apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
4 General

Unless otherwise specified, all tests shall be carried out at standard temperature (see ISO 23529).

5 Apparatus

5.1 Pressure source, capable of applying pressure at the rate specified in 7.2.2, up to the required test

pressure.

5.2 Calibrated pressure gauge or pressure transducer with digital readout, chosen for each test

so that the test pressure is between 15 % and 85 % of the full-scale reading.

In the interest of accuracy, calibrated pressure gauges or pressure transducers with digital readouts shall

be checked at frequent intervals and the fitting of restrictors is recommended to minimize shock damage.

5.3 Dimensional equipment, sliding vernier callipers or micrometer, length measuring tape,

circumferential measuring tape (π tape).

6 Test pieces
6.1 Hose assemblies

When hose assemblies are to be tested, the manufactured assembly length shall be used for the test.

6.2 Hoses

The hydrostatic pressure and burst tests shall be carried out on a hose test piece with a minimum free

length, excluding end fittings and end reinforcements, of 600 mm when deformation is to be measured

and 300 mm when it is not. When a longer test length is required for a particular hose type or size, it

must be specified in the individual hose product specification.

At least two test pieces shall be t
